In
this article I am going to explain how to add a row in gridview to insert the record
into database on add new button click in asp.net.

Add
row in asp.net Gridview on button click using C# and vb.net
|
In
the previous article I have explained how to avoid (prevent) duplicate recordinsert on page refresh in asp.net , how to auto generate and display Serialnumber (row number) in asp.net gridview and how to check uncheck ORselect/deselect checkboxes in asp.net gridview control using Jquery.
We
have 2 ways to implement this functionality. 1st one to add
new row to Gridview dynamically (code behind). To implement this refer to this
link how to add multiple rows to Gridview control dynamically in asp.net. 2nd
is use the Gridview FooterTemplate. Put all the required control in footer template
and enable the footer template on button click.
Implementation:
HTML
